Microthermal Field-Flow Fractionation | |||||

Rok: 2008 AnotaceMicrothermal field-flow fractionation (micro-TFFF) is a new method of polymer and particle separation and analysis based on the effect of thermal diffusion (Ludwig-Soret effect); the relationships between molecular characteristics of the separated macromolecular and particulate species such as molar mass, particle size, chemical nature, and composition; and their distribution and separation characteristics such as retention. The book begins with a description of the theoretical principles of FFF, which apply equally to micro-TFFF, although the latter technique offers a number of important operational advantages, including superior cold-wall temperature regulation. Practical analytical aspects of experimental data analysis are discussed in detail. Typical methodological applications of micro-TFFF are given for polymers and particles of synthetic, natural, or biological origin. The book will be of interest to university and R&D scientists involved in the analysis and characterization of polymers, biopolymers, particles, and biological cells in polymer chemistry, colloid and interface science, microbiology, and the environmental sciences.
